Definitions

  • the present model describes the technical field of parts for the automobile sector, more specifically a device applied in the starter unit that constantly works geared to the main engine.
  • the new model presents a start-up unit that works with a drive gear constantly engaged to the gear train of the main engine; a torque transmission system and free wheel with rollers and cam; and a damping system to avoid damages to the start-up system when the combustion engine turns off due to kickback that is a characteristic present in all combustion and explosion engines.
  • the start-up unit obtains gains and improvements in the manufacture and resistance of the equipment, as well as more efficiency in the freewheel system.
  • an electric start-up engine In practically all vehicles that have internal combustion and explosion engines there is the presence of an electric start-up engine. This, in turn, is made up of two parts, an electric part and a mechanical part.
  • the electric part basically consists of a solenoid and an armature.
  • the mechanical part is responsible for the casing, linkage lever and starter.
  • the starter has the primary function of transmitting torque from the electric engine to the internal combustion engine. This torque is limited by the construction of the starter and materials used.
  • the combustion engines have a minimum rotation regime to operate called slow run, this being at least twice greater than the start-up rotation. Due to this condition, the starter has a secondary function called freewheel, which is highly important to avoid the over-rotation of the start-up engine.
  • the present model has the same principle as PI0804052-4 A2, where the start-up unit remains constantly engaged and coupled to the engine, However, it has a new device in the clutch(s) that operates with rollers and cam, providing the freewheel system with more resistance and efficiency; a damping system to avoid damages to the start-up system; and new devices in the internal parts of the unit that when united make up a more efficient, economic, silent and longer lasting start-up system.
  • the start-up unit comprises an electric engine, a back bearing, where two planetary gear assemblies are positioned (each consisting of a crown, satellite gears and planetary pins), a shaft with sun gear and bushings; a front bearing, two rollers, pressure rings, washers, and a drive gear, consisting of the drive gear of the unit, working constantly engaged to the gear train of the main engine; for having a new device in the assembly of the freewheel system that operates with rollers and cam, and for presenting a rubber damping system to avoid damages to the start-up system.
  • the present model starts operating when the start-up key of the combustion engine is turned.
  • the start-up key transfers current to the electric, which in turn puts the armature into motion.
  • This movement is transferred to the reduction system by planetary gears that modify the torque and output rotation of the system, making it ideal for the combustion engine to start operating.
  • planetary gears that modify the torque and output rotation of the system, making it ideal for the combustion engine to start operating.
  • cam and rollers system that has the function of transmitting torque in one of the rotation directions and freewheel in the opposite direction;
  • rollers are always being forced by the spring to stay in contact with the shaft and cam to ensure the mechanical contact in the direction of the lock torque.
  • the user of the engine stops the start-up by turning the start-up key to the neutral position.
  • the electric engine is de-energized, ceasing the movement of the armature and consequently the planetary gears. Therefore, only part of the system (gear, shaft and one-way clutches) continues to move coupled to the combustion engine and to work in freewheel in relation to the rest of the start-up system.
  • start-up unit (1) used to transmit initial torque to the combustion engine (M), consisting of drive gear (9), constantly working engaged to the gear train (T) of the main engine (M); it contains a new device in the freewheel assembly (2) that operates with rollers (5C) and cam (5A2), and having a rubber damping system (8), and reduces the bumps in the engine and therefore, avoids damages in the start-up unit (1).
  • the figure (01) shows the start-up unit (1) in an exploded view, showing the following: the electric engine (A); a back bearing (B); where a planetary gear assembly (C) is located in the internal part (each consisting of a crown (D), satellite gears (E) and planetary pins (F)), and on the outer part, a planetary gear assembly (C1) (each consisting of a crown (D1), satellite gears(E1) and planetary pins (F1)); a shaft with sun gear (G) and bushing ring (H); a freewheel system assembly (2), consisting of a cylindrical shaft (3) with spare cylindrical base (3A) having three holes (3B); an intermediary cylindrical bearing (4), contained inside the semi-cylindrical cavities (4A), to insert the projections of the crown (D1), and a bearing ring (4B), for the spare cylindrical base (3A); two one-way clutches (5), each consisting of a cylindrical compartment (5A), equipped with a fixed ring (5A1), internal walls with cam (5
  • Figure (02) shows the perspective view of the start-up unit (1), which shows the electric engine (A); the back bearing (B); intermediary bearing (4); front bearing (1); and the drive gear (9).
  • Figure (03) shows the section view of the start-up unit (1), showing on the external part the electric engine (A), back bearing (B); intermediary bearing (4), front bearing (I), and the drive gear (9); and the internal part showing the crown (D1), satellite gears (El), cylindrical shaft (3) with spare cylindrical base (3A), the one-way clutches (5), spline shaft (7) and the rollers (J).
  • Figure (04) shows the top view of the damping system (8), which shows the coupling (8A) in the internal part to insert the end with the spline (7B) of the spline shaft (7) and three rods (8A2) on the external edges, to insert the damping rubbers (8B), which are inserted in the cavities (9A) of the internal walls of the drive gear (9).
  • Figure (05) shows the section view of the freewheel system (2), which shows the cylindrical shaft (3); one-way clutch (5), with the internal walls with cam (5A2); spring guides (5B); rollers (5C); oblong springs (5D); the cage (SE), with the housings (5E2); and the front bearing (I).
  • the figure (06) shows the exploded view of the one-way clutch (5), showing the cylindrical compartment (5A), equipped with a fixed ring (5A1), internal walls with cam (5A2), a lock ring (5A3) of the internal assembly, which consist of spring guides (5B) comprising rectangular bases and oblong pins, rollers (5C), oblong springs (5D) and a cage (5E), equipped with a ring (5E1) and guide supports (5E2).
  • spring guides (5B) comprising rectangular bases and oblong pins, rollers (5C), oblong springs (5D) and a cage (5E), equipped with a ring (5E1) and guide supports (5E2).
  • FIGs (07) and (08) shows the installation of the start-up unit (1), which shows the drive gear (9) constantly engaged to the gear train (T) of the main engine (M), more specifically in the power socket.
  • Figure (09) shows a starter found in the current start of the art, which shows the displacement of the pinion on the flywheel rack.
  • This start-up unit aims to show reduction in manufacturing cost, performance improvement, considerably noise reduction, life increase, and elimination of some of the existing components in the conventional start-up system.
  • the parts of this assembly can vary in size, shapes and materials to adapt to any type of start-up unit system, but always maintaining the same characteristics of the present model.
